Thank you for your answer.
I know very well that the change list for an ideal product is infinite.
I'm just trying to bring my stone to the edifice.
Insofar as the Gypsy style is available (for finance), I allowed you to report these small gaps and the uselessness of the Gypsy Bossa sub-style since it is identical to the Gypsy Swing sub-style.
I am not in a hurry.
Good luck to developers.
Sincerely
